I BRAKE AND LOOK FOR SLIDING SASHES.

Specification of Letters Patent.

Application filed May 16, 1918; Serial No. 235,024.

T 0 all whom it may concern Be it known that I, ELMER M. HICKS, a citizen of the United States, and a resident of Schenectady, in the county of Schenectady and State of New York, have invented a new and Improved Brake and'Lock for Sliding Sashes, of which the following is a description.

My invention relates to means for holding sliding window sashes when open to any desired extent and for locking the sashes in the closed position. The invention particularly relates'to sash attachments involving the use of brake or stop elements adapted to frictionally engage a guide rod on a window frame for holding the sashes in any given adjustment.

The general object of my invention is to provide a device of the character indicated, adapted to be applied to upper and lower sashes respectively, and improved in various particulars whereby characteristic results are obtained among whichare the following: The friction brake elements may be readily adjusted to vary the pressure on the guide rod; locking elements are carried by the brake device to lock automatically with a relatively fixed element when a sash is in the closed position, and the various parts are so formed and arranged as to promote convenience in theirassem'blage, as well as strength and durability.

Reference is to be had to the accompanying drawings forming a part of this specification.

Figure 1 is a front elevation of a window having my invention applied thereto;

1 Fig. 2 is a vertical section on the line 22,

Fig. 3 is an enlarged side elevation of the devices relating particularly to the upper sash, a portion of the vertical guide rod common to the devices of both sashes being included;

Fig. at is an inverted plan view of the features shown in Fig. 3, the guide rod being in section;

Fig. 5 is a rear view of the carrying bracket shown in Figs. 3 and 4;

Fig. 6 is a side elevation of the lower sash attachment with a portion of the guide rod;

Fig. 7 is an inverted plan view of the features shown in Fig. 6, the guide rod being in section.

In the drawings the letter A indicates an upper sliding sash; B, a lower sliding sash,

and C, the window frame. The attachment for the upper sash includes a bracket 10 of general U-shape which preferably has cross braces 1'0 therein between the top and bottom arms of the bracket and said bracket is of a size that when secured to the upper sash the front will lie beyond the lower sash B.

Patented Nov. 5.191s.

The securing means for the bracket preferably consist of feet 11' thereon and having screw holes 12, which feet, however, are not formed directly on the bracket 10 but on adjustable bars 13, lying against the outer faces of the upper and lower arms of the bracket and formed with slots 14: receiving adjusting screws 15 which take at their ends into the arms of the bracket as indicated at 16, Fig. 3.-

A friction stop or brake is provided, carried by the bracket 10 at the front and comprises a block or plate 17 rigid with said bracket and a relatively adjustable friction plate 18, between which elements 17, 18(is disposed a fixed guide rod 19 secured, as hereinafter described, at its upper and lower ends tothe window frame 0. The block 18 also, into the bracket 10 as indicated in Fig. 3, said screw being positioned at one sideof the guide rod 19. At the opposite side of V the guide rod 'a thumb screw '21 passes through the plate 18 andsecures the same to 'the block 17 and bracket 10. The screws, 20, 21, pass-loosely through the plate 18 and on the shank of the screw 21 is a tension spring 22 for varying the pressure of the elements 17, 18 on the guide rod 19.

The arrangement is such that the upper sash having applied thereto the bracket 10 carrying the brake blocks, will be held by the latter when the window is opened to any desired extent and the braking friction on the rod 19 may be varied by turning the screw 21 as will be obvious, the looseness of the screw 20 permitting of the adjustment of varying the friction by the screw 21.

The upper end of the guide rod 19 is bent laterally to provide an arm 23, the end of which is secured as at 24 by a screw or the like to the frame B. A brace 25 is secured at its lower end of the arm 23 of the guide A and at its upper end to the top of the window frame Cas at 25. The said arm 23 is adapted to be engaged by a latch 26 which is pivotally secured by a screw 27 or the like to the block 17 or any equivalent relatively the latch 26 may vibrate on its pivot 27 to a limited extent for engaging or disengaging the arm In practice, when it is desired to unlock the sash A, the latch is rocked into disengaged position by a finger of the operator while at the same time the sash is grasped to lower the same to any desired extent, the sash being held by the friction of the blocks 17, 18 in any given position.

Substantially the same elements described are applied to the lower sash B, to frictionally engage the rod 19 and to lock the sash in the closed position. Thus, a bracket 10" is of a width that when the bracket is applied to the lower sash B, the parts carried thereby will be in position to coact with the rod 19 for holding or looking the sash. The bracket has securing feet 11 integral thereof.

On the face of the bracket is a block 17 and a friction block 18 is provided, said elements 1?, 18", corresponding with the elements 17, 18 and lying respectively at the back and front of the rod 19. Screws 20 21. and a spring 22 are arranged in connection with the elements 17 18 and corresponding with the similar elements previously described. Also, a latch 26 is pivotally secured to the block 17 by a screw 27 and is inverted with respect to the latch 26,

the arm 28* corresponding with arm 28, being pendent and terminating in a hook 29 which is adapted to engage an arm 23 at the lower end of the rod 19. A brace is secured at its upper end to the arm 23 and at its lower end as at 25, to the window frame. The arm 23 is adapted to be engaged by the hook 29 and in the manner de scribed in connection with the latch 26.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claim.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

An attachment for windows with sliding sashes, said sashes including a guide rod adapted to be secured to the window frame, a bracket adapted to be secured to a sash, a friction element rigid with the bracket, a second friction element, the guide rod being adapted to be received between said friction elements, a screw loosely securing the second friction element to the first friction element at a side thereof, a second screw serving to secure the second mentioned friction element to the first friction element at the opposite side thereof from the first screw, whereby the guide rod may be accommodated between said screws, and a tension spring on the shank of the second screw and subject to the action of the latter to vary the tension of the spring on the second. friction element.
